Quercus mongolica, Fisch. Tree, to 100 ft.: branchlets glabrous: lvs. on very short petioles less than 1/4in. long, obovate to obovate-oblong, obtuse at the apex, narrowed toward the rounded or auriculate base, coarsely toothed or sinuately lobed, with short and broad usually obtuse or obtusish teeth, dark green above and glabrous, paler green and glabrous beneath or pilose on the veins only, 4—8 in. long: fr. several or solitary on a short stalk or nearly sessile; acorn ovoid or ellipsoid, about 3/4in. long, embraced about one-third by the cup which is grayish tomentulose with thickened tuberculate scales, thinner and acuminate at the slightly fringed margin. E. Siberia, N. China, Korea, N. Japan. Var. grosseser- rata, Rehd. & Wilson (Q. grosseserrata, Blume. Q. crispula, Blume). Lvs. somewhat smaller, usually acutish at the apex with acute or acutish sometimes denticulate teeth: cup with thin closely appressed scales, not fringed at the margin. Japan. S.I.F. 1:27.— Some Japanese botanists distinguish Q. crispula as a species by the hemispherical cup inclosing the acorn about one-half from Q. grosseserrata which has a saucer-shaped cup inclosing the acorn one-fourth or one-third, but many specimens are intermediate in this character, and, as the lvs. of the two forms are exactly alike, it seems hardly possible to distinguish these two forms as varieties. Var. grosseserrata has proved perfectly hardy at the Arnold Arboretum and forms handsome trees of vigorous growth.
